The product’s double-wall design helps maintain exhaust heat and reduces exterior surface cooling. Choose this if you need a quick, insulated extension rather than a long run.
Caution: Verify compatibility with your stove or appliance collar, as connector dimensions can vary. Short segments may require additional pieces for a complete run.

Best for users needing to adapt different duct sizes, this Yaocom increaser converts a 5-inch pipe to 6 inches. It supports versatile ventilation setups, making it suitable for garages, attics, or kitchens that require compatibility with multiple duct systems. The crimp design at the collar allows easy installation and a snug fit without tools.
Limitation: It’s a reducer accessory, so plan for a complete run with compatible 5-inch and 6-inch components to avoid gaps or leaks.
DuraVent 5GV12 5″ Inner Diameter Type B
This Double Wall Type B gas vent pipe offers a robust 5-inch inner diameter with a 12-inch length. It’s best for longer, insulated vent runs where maintaining heat and minimizing exterior condensation matter. The double-wall design provides an extra barrier for venting hot gases.
Better for: gas venting scenarios that require a longer, insulated segment. Limitation: This section is 12 inches long, which may require additional fittings for shorter runs.
5M4 Double Wall Vent Pipe 5 in. x 4 Feet

Buying Guide: Key Considerations for Double Wall Stove Pipe
- Size compatibility: Match the pipe diameter to your stove outlet and any adapters. A mismatch can cause leaks or poor draw.
- Length and fit: Plan runs in full or modular segments. Longer sections reduce joints but require appropriate supports.
- Material and insulation: Double-wall pipes improve heat retention and reduce exterior temperatures; verify that materials are rated for your vented fuel type.
- Installation ease: Crimped collars or tool-free connectors simplify assembly, especially in tight spaces.
- Vent type: Type B gas vent vs. direct stovepipe; choose according to appliance type and local code requirements.
- Ingress protection: Ensure joints are sealed and properly secured to prevent gas or smoke leakage.
